Issue #5054 has been updated by Kenta Murata.
I feel the proposed syntax including e+nd by ko1 is ugly, as nested end chains are so.
They tell us the code must be made refactoring avoiding use them.
So, we can expect well-trained people avoid using them.
BTW, the proposed syntax reduces the height of code.
I like this advantage. I want to merge this.

Feature #5054: Compress a sequence of ends

Though as matz said at rubykaigi2011 ruby is a quite good language, many people hate a long sequence of `end' like this:
module MyModule
class MyClass
def my_method
10.times do
if rand < 0.5
p :small
end
end
end
end
end
So, I'd like to propose introducing a special keyword, en(n+)d. Using this keyword, we can rewrite the above example like this:
module MyModule
class MyClass
def my_method
10.times do
if rand < 0.5
p :small
ennnnnd
I know matz's already rejected a python-style block. He wrote:

These bad things won't occur by introducing en(n+)d.
Some implementations already exists.
